With geographic information system (GIS), the ecological water requirement for forests in the Jinghe watershed, western China was estimated.

Using the ArcView Geographic Information System (GIS) platform, a case study was carried out by selecting the population of Pinus massoniana from a needle-and broad-leaved mixed forest community in the Heishiding Nature Reserve, Guangdong Province.

In this study, remotely sensed data and the geographic information system were applied to analyze the changes in land cover along topographic gradients from 1978 to 2001 in Beijing, a rapidly urbanized mega city in China.

The priority analysis using the geographical information system (GIS) tool has revealed that castern provinces should be of high priority in the future reduction activities of dioxins release in China.

Spatial distribution of ecological security status assessment of West-Liaohe River based on geographic information system

In this paper, some problems for Large Scale Systems theory are discussed. There are: what the Large Scale System (LSS) is; the relationship between LSS' theory and control theory; the relationship between LSS' theory and System Engineering; the relationship between LSS' theory and Cybernetics; the special problems of LSS' theory. In author's opinion, LSS' theory is the important part of the third age of control theory, i.e. the fundamental of the total complex automation. On the other hand, LSS' theory is...

In this paper, some problems for Large Scale Systems theory are discussed. There are: what the Large Scale System (LSS) is; the relationship between LSS' theory and control theory; the relationship between LSS' theory and System Engineering; the relationship between LSS' theory and Cybernetics; the special problems of LSS' theory. In author's opinion, LSS' theory is the important part of the third age of control theory, i.e. the fundamental of the total complex automation. On the other hand, LSS' theory is the new stage of development Systems Engineering——Dynamical Systems Engineering. It may also be said, LSS' theory is the new branch of cybernetics ——LSS' Cybernetics. LSS' theory is not the classification of the size of various systems, but it's the methodology of the analysis and synthesis of large complex control and information system. It is the system science of large scale systems.

Relationship between the superficial mineral and their indicator plants in an airborne remote sensing test area has been investigated by ways of the chemical analyses of both superficial mineral and trace elements in those plants and, especially, the field spectral analysis. The former two analyses, showing the mineral contents in the defectively growing plants, can directly indicate the existence and amount of mineral in that area. The existence of mineral in a certain kind of plants, as observed, always make...

Relationship between the superficial mineral and their indicator plants in an airborne remote sensing test area has been investigated by ways of the chemical analyses of both superficial mineral and trace elements in those plants and, especially, the field spectral analysis. The former two analyses, showing the mineral contents in the defectively growing plants, can directly indicate the existence and amount of mineral in that area. The existence of mineral in a certain kind of plants, as observed, always make the plant to reflect a particular spectrum and the different minerals contained in plant present their own spectra respectively. Such characteristic spectra are available to reveal the existence of mineral or rocks which are covered by proper vegetation. Thus, a new information system is developed as the characteristic geological data to air or space-borne remote sensing. It may serve to provide the fundamental data for discriminating one from another in the pictures remote-sensed by airplane or satellite. Therefore, it will be a new method to the geophysical prospecting.
